NEW YORK – Jim Miller will carry a heavy heart into Saturday’s UFC on FOX 3 headliner with fellow lightweight Nate Diaz.

But it’ll be covered on his way to the cage with a TapouT walkout shirt he hopes will raise some serious funds for his nephew’s foundation.

Miller, who fights in his home state for Saturday’s network-televised event, and clothing giant TapouT are donating $10 from every shirt sold to a foundation set up for brother and fellow UFC fighter Dan’s young son.

“We did a signature limited-edition T-shirt with TapouT, and they were generous enough to donate at least $10 per shirt to my nephew’s foundation, the Daniel James Miller Foundation,” Miller said of the project.

The DJM Foundation is named after “Danny,” who was born to Dan and Kristin Miller in January 2010 with autosomal recessive polycystic kidney disease (PKD). He undergoes daily dialysis and physical therapy after losing all kidney function. An upcoming kidney transplant is scheduled, but Danny will remain on costly anti-rejection medication for the remainder of his life.

The foundation has been set up to help with the costs of the transplant and medication, which aren’t covered by insurance. The UFC was one of the first supporters of the foundation, and now TapouT has lent its support.

“It was a very generous move by them,” Miller said. “I’m really excited to work with them.”
